Abstract

A new rinse-free shampoo has been developed. The shampoo includes a biodegradable absorbent formed of a cross-linked carboxymethylcellulose which allows a higher water content than conventional shampoos. The soaps used in the shampoo to provide the cleaning action are preferably lauric acid derivatives, including ammonium derivatives. The shampoo leaves less residue than conventional rinse-free shampoos.

Description

[Detailed description of the invention] No-rinse shampoo 11 Chisato 1j This application is filed March 9, 1989 and is entitled "Biodegradable Superabsorbent Sponge" Continuation-in-part of U.S. Patent Application No. 320,944 and filed March 8, 1990. Continuation-in-part of U.S. Patent Application No. 490,356 entitled "Particulate Absorbent Materials" It is a wish.

Bean bean ball 1 The present invention relates to novel detergents such as shampoos.

In particular, the present invention leaves less residue than conventional no-rinse shampoos, yet has a high The present invention relates to a no-rinse shampoo having a high water content.

Menzudate 11 Regular shampoo consists mainly of water, detergents such as sodium dodecyl sulfate, and thickeners. agent, foam enhancer and flavoring agent. These shampoos are often Although they provide completely acceptable hair cleaning, they It takes a lot of water to rinse out the pool. In most cases this is However, rinsing is recommended for people with frail bodies, such as geriatric patients and people with other illnesses. This is a serious problem for hospitalized patients. Appearance is still an important factor for these people. However, since they are mostly bedridden, they cannot use normal hair washing methods. cannot be used easily. Therefore, a few years ago, "no-rinse" shampoos were introduced. It has been developed. No-rinse shampoos rub into the hair, which removes dust particles. It is used to trap or chelate oils and oils, and then towel the hair. removed by wiping and/or combing or brushing. Ru. The term "no-rinse shampoo" as used herein refers to additional shampoos for its operation. A shampoo that requires little or no liquid.

While traditional no-rinse shampoos have had some success, this They have two major problems. Firstly, these are the same as traditional shampoos Didn't clean the hair like that. Secondly, they leave a lot of residue on the hair. There was a tendency to leave residue behind. This residue (this is chelated dust, shampoo (often containing particulate matter from itself or other particulate forms) It leaves a dull, unclean appearance, interferes with the pleasant appearance consumers enjoy, and damages the scalp. May cause itching and scratching. Furthermore, conventional shampoos are made of natural oils. I've washed away a lot.

Traditional no-rinse shampoos have sodium lauryl sulfate as their main ingredient. was. This is because the addition of ammonium ions poses a residue problem. It is from. Current no-rinse shampoos contain triethanolamine lauryl sulfate. substances such as carbon dioxide, propylene glycol, and small amounts of cocoamidojetanolamine. is used. However, these modified formulations are Solve the problems caused, especially the greasy and/or sandy feel of the final hair. Never.

Therefore, it is an object of the present invention to solve the problem of residue build-up and to provide an inexpensive solution to the hair. To provide a shampoo that does not require rinsing and provides a clean and shiny appearance.

Another object of the present invention is to use shampoos for camping or other situations where conventional shampoos cannot be used. To provide a biodegradable, no-rinse shampoo that can be used for the purpose of That's true.

Yet another object of the invention is to provide shampoos for geriatric patients and other frail patients. The goal is to provide the following. These and other objects and features of the present invention are as follows: It will become clear from the description.

Menzu Riho 1 The present invention is suitable for use in shampoos containing gel-like absorbents and having a high water content. It features a cleaning agent for humans. When used as a shampoo, It works in a rinse-free manner without leaving any significant residue on the hair, thus can provide better cleaning action than conventional no-rinse shampoos.

The human cleaning agent of the present invention preferably has an organometallic crosslinking agent as its main component. carboxylated cellulose material, soap and water, cross-linked and stabilized by have The human cleanser is preferably a shampoo, most preferably a no-rinse shampoo. It is in the form of a dumpling. Preferred carboxylated cellulose materials include carboxy Methylcellulose, especially a high DS (degree of substitution) value, most preferably a D of 0.5 or more It is carboxymethylcellulose with an S value. Preferred organometallic crosslinkers are: Aluminum complex ions such as aluminum acetate stabilized by oxalic acid It contains. Other metal ions such as ferric ions can be used. Although aluminum ions appear to provide the best crosslinking.

Although any soap can be used in the shampoo of the present invention, preferred Soap contains lauric acid itself, sodium lauryl sulfate, and lauryl sulfur. Ammonium succinate, laurylamide, laurylamide jetanolamine, Lauric acid derivatives such as lauryl betaine and mixtures thereof. Laurin Other amides such as jetanolamide, chlorides or sulfates of acids may also be used. can do.

Preferred shampoos have a high water content, but this water accounts for 90% by weight of the shampoo. occupies more than This high water content and the resulting low solids content creates a Enables proper cleaning with little residue left behind.

Further features of the invention will be described in connection with the following description.

1 day of crying and 1 story” 1st viewing Even when the shampoo of the invention is used in a non-rinsing manner, e.g. - without any residue build-up even when no water rinsing is used to remove Provides excellent cleaning action. This is due to the shampoo's high water content (low solids content) and an absorbent gel that traps dust without leaving any residue. This high content The amount of water should be adjusted so that the shampoo and any trapped dust are removed by toweling and/or combing the hair. It means that it is easily removed by scraping.

The shampoo of the present invention is a cross-linked carboxylated cellulose material that acts as an absorbent. Based on quality use. This absorbent has high ability to retain aqueous solutions , thus higher water contents can be used without making the shampoo "run-off" . This absorbent is biodegradable and substantially non-allergenic. Regarding this absorbent Further details may be found in U.S. Patent No. 320,944 and U.S. Pat. It is described in No. 0.356.

Although any soap can be used in the shampoo of the present invention, Lauri Certain of these soaps, for example lauryl acid derivatives are preferred. Sodium sulfate is commonly used in shampoos. In addition, shampoo is cheap. Contains various other substances including fixing agents, conditioners, foam enhancers and fragrances can do.

Jacketed stainless steel kettle with blade mixer Add deionized water (96,5%) and, while stirring, pour it into, e.g. Heat to 70-80°C by passing through a steam. Two types of preservatives are added to this water: Add methylparaben (0.2%) and propylparaben (0.03%). Ma Also, compounds such as d-bantanol, cetyl alcohol and cetearyl alcohol A conditioner can also be added at 0.3-0.5% of the total weight. The solution is preservative Stir until the agent is completely dissolved. The resulting solution is then passed through a homogenizer mixer. Transfer to another stainless steel kettle with The CMC/crosslinker powder is then mixed to ensure that there are no lumpy formulations. Add under high speed mixing and mix until homogeneous. This result Materials may be stored overnight, for example, to minimize air bulges in the final product. Ru. CMC is cross-linked by aluminum acetate/bolate and its aqueous solution swells with
